An earpiece allows Security Professionals to communicate in a covert manner without anyone noticing. Earpieces are important to allow communication between the wearer and his/ her team discreetly. There are many earpiece models and makes that a security agent can wear but typically, earpieces are of two major categories i.e. wireless and wired. Within these two categories, there are varying versions and models available. Several factors affect the choice of the ideal earpiece, these factors include:

• Discreetness- Security officials can chose an earpiece based on how discrete they want to be. The level of discreetness is determined by the earpiece style and colour of the coiled tube. In-the ear earpieces are obviously discreet because they are worn inside the ear than over-the ear earpiece- with the wires and all. You can choose a colourless earpiece as opposed to a coloured one for more secrecy or choose a wired earpiece altogether for total secrecy.

• Comfort- You obviously want the earpiece you chose to be comfortable to wear. Choose an earpiece that fits well and that is made with hypo allergic materials. Some of the important questions to ask before choosing an earpiece include how easy the earpiece is to wear and remove, how easy is to use and control the device, can the earpiece remain intact as long as necessary without falling off.

• Versatility- The right earpiece should make it possible to wear underneath the clothes, attached to a collar or back of the tie.

• Tastes and preferences- Different individuals have different tastes and preferences. You can chose an earpiece that meets your needs and preferences in terms of comfort, style and colour

A security earpiece is normally worn inside or put around the ear depending on the type you choose and is usually connected to a 2- way radio or related device. An earpiece is also worn with a microphone and receiver that makes it possible for a person to communicate with other people wearing a similar earpiece.

Earpieces are normally won by bodyguards and security personnel for instance the US secret service, law enforcement officers and private bodyguards and security personnel to allow discreet communication for security purposes. Earpieces are either wired or wireless, with each type having different models, types, styles and makes

Earpieces can either be worn around the ear or in the entrance of the ear as a small ear bud. For extra discreetness, wireless earpieces are often preferred over wired ones since it’s hard to tell that someone is actually wearing a wireless earpiece as opposed to a wired earpiece. Wireless earpieces often receive signals wirelessly. A person needs to wear a separate microphone at the end of a sleeve or on a lapel. To send a message, the wearer needs to speak into the microphone and receive messages via the wireless earpiece

A wired earpiece works in the same way as a wireless earpiece the only difference is that the receiver is connected to the earpiece with a wire that anyone can see. However, the wire can be transparent to make it harder for people to notice. The wire is normally worn around the back of the ear to get out of the wearers way.

There are different types of wired earpieces including one wire, two-wire and three wire. One wire microphone consists of a single wire and no microphone, two- wire comprises of an earpiece and a single wire connecting the earpiece to the microphone which is usually connected to a sleeve or lapel.

A three-wire earpiece comprises of an earpiece, a microphone worn on the lapel, and a third wire that normally connects to a separate device on the hand to allow the wearer to activate the microphone at his discretion.

As mentioned above there are typically two types of earpieces and a wide variety of models under each type. The ideal earpiece will be determined by the wearer’s preferences, level of secrecy wanted, cost, comfort, and how versatile the device is.

The market is flooded with various models and makes so it’s important to understand your needs before buying an earpiece. Buy your earpiece from a reputable source. Do some research before buying your ideal security earpiece to understand the features, components, advantages, and disadvantages.

What Can Visual Communications Do?

In a word?  Everything. Visual communication is the conveyance of ideas or meanings via visual images. This includes everything from illustration to logo design, from typography to road signs.

Employing visual communications in your business is a great way to increase your brand awareness. Today, corporate entities and their associated products can be readily identified worldwide, simply by an act of visual communication.

Consider the ‘McDonald’s Golden Arches’ Logo. When it is placed on a road sign, this logo is usually only accompanied by the number of miles away the nearest restaurant is. This suggests that the logo itself is so well known that no text is needed to explain it.

The Nike ‘Swoosh’ is another prominent example, as is Apple’s, um, Apple.

The subject of the corporate world’s reliance on visual communication (together with its effect on the rest of us) was covered extensively by Naomi Klein, one of our favourite authors, in her 2000 bestseller, ‘No Logo’. She says,

“Advertising and sponsorship have always been about using imagery to equate products with positive cultural or lifestyle experiences. What makes nineties-style branding different is that it increasingly seeks to take these associations out of the representational realm and make them a livid reality. So the goal is not merely to have child actors drinking Coke in a TV commercial, but for students to brainstorm concepts for Coke’s next ad campaign in English class.”

If you’re looking for a definitive answer to your question, look no futher than ‘No Logo’.

Visual communication can be used to convey instant meaning, which is especially good for road signs. Typically, road signs contain no words, just an image representing the thing that motorists are supposed to be aware of. A figure of a man digging up the road, for example, denotes roadworks ahead (although, to be fair, it also looks as if he could be putting up an umbrella). A silhouette of a deer (or, in Australia, a kangaroo) indicates the presence of animals in the area that may pose a danger to motorists (or themselves).

It is also used as a sort of communicational shorthand, with increasing levels of cross-cultural complexity. For example, horror movies would once have been advertised with a typeface made from blood, or slime, to convey the ‘horror’ of the movie. However in today’s world, such advertising would only be used in pastiche horror movies, or else horror movies that were being made to invoke a bygone era. Movies that used a stereotypically ‘ethnic’ typeface (such as to evoke a now-problematic ‘Chinese’ or ‘Indian’ feel), might now find that those typefaces are used for movies knowingly aimed at Asian American or British-Indian audiences.

Visual communication can provide a wealth of information in just one simple image, or a few words. The ‘Star Wars’ typeface, for example, evokes the science fiction film franchise, even if all it says is “Danger: High Voltage” or similar.

What is a Communications Engineering

Communications engineering is a disparate array of technological disciplines brought together under one all-encompassing banner. The disciplines considered to be part of a communication engineer’s skill set include telecommunications, mobile phone networks and Internet maintenance (but are by no means limited to those examples).

As we wrote earlier this month, any technology that aids in communication, from a walkie-talkie to a Skype account, is technically a communication technology; therefore, it also follows that anybody who works in these different areas can call him/herself a ‘communications engineer’.

The theory behind this move is that communications technology is becoming more streamlined and, to some extent, more homogenized (think of the ubiquity of mobile phones and social media) and so, it makes sense to bring communications technology together as a single subject as well.

As I type this, it is actually possible to get a Degree in Communications Engineering (as a single subject) from many universities worldwide. However, communications engineers frequently hold other Degrees such as electrical engineering, physics, telecommunications and/or computer science.

The sort of students that apply for courses like this (and subsequently work in the related areas) are generally logistically minded, tech-savvy people who are comfortable learning new skills and adapt quickly to new technology. Certainly, the money can be good for a decent engineer with a good reputation and an up-to-date skill set. Industries that rely on the expedient exchange of information (news networks, the stock exchange, big businesses and etc) should be the goal for the ambitious communications engineer (as well as the eager graduate).

Communications engineering is a vast and somewhat esoteric subject, because it combines so many different disciplines. Ideally, good communications engineers would be just as able to handle microwave engineering as they would a downed computer network, so it takes a smart cookie to be really good at the job.

Communications engineers are often quite business savvy as well. A big part of the job is dealing with clients or management, making presentations and working effectively as part of a team. Experience of modern business practice is not essential, but from the looks of things, it certainly helps.

The vast majority of communications engineers work for specific telecommunications companies and/or manufacturers, although some are self-employed as consultants or on fixed contracts.

According to Targetjobs.co.uk, typical job responsibilities for a communications engineer include: undertaking site surveys, agreeing to and staying within a client budget, staying up-to-date with technological information, problem solving (obviously!), creating test procedures, creating ‘worst case scenario’ plans for companies to follow and presenting companies/clients with the best way to manage their communication systems.

What Is A Two Way Radio And Who Uses Them?

A two-way radio is basically a radio that is structured to transmit and receive. In general, most voice-wireless communications technology, counting cellular systems, are categorized by two-way radio definition. Usually, a two way radio refers to a radio system primarily utilized for group call communications. This two-way system is also called PAMR Public Access-Mobile Radio, PMR Private-Mobile Radio, LMR Land-Mobile Radio, and PMR Professional-Mobile Radio.

Portable 2 way radios are frequently called “walkie-talkies” or “handie-talkies.” Not much different from “handie,” the term sometimes used to describe mobile phones. While we’re on the subject, it’s probably best to get something out in the open right now. People often interchange the terms two-way radio and walkie-talkie.

However, walkie-talkie is chiefly a generic or slang-term for hand portable two way radios. Moreover, the term usually implies non-professional, license free, consumer type, or “toy” equipment. When referring to two way radios, people are basically talking about professional licensed equipment. A walkie-talkie is generally a hand-held CB radio. A 2 way radio is of superior quality and utilizes much higher frequencies. Two-way radios can also be found in mobile and base-configurations in addition to using radio network-infrastructure.

In addition, two-way radios are usually decked out with a PTT or “Push-to-Talk” key to trigger the transmitter. Users simply press the PTT key and quickly begin a conversation. The user lets go of the PTT key in order to hear others.

A two-way radio user can talk immediately with other radio users or utilize radio network-infrastructure. A direct-talk amongst radios, normally referred to as direct more operation/talk-around mode, has restricted reach because of limited radio power. To defeat this restriction, a radio network-infrastructure can be used to expand the communication range.

WHY USE A TWO WAY RADIO?

With numerous choices in wireless technology today and with 2 way radios being one of the first wireless devices, some wonder if this type of radio is still a useful gadget in the current world of technological communication. Well actually yes. There are two main features that differentiate two-way radios from other wireless gadgets:

-Instantaneous Communication

Two-way radios offer instant communication. Users can simply press the PTT or “Push-To-Talk” key and inside a fraction of a second, the user can instantly speak and convey their message. This is because of the quick-call setup time entrenched in the technology. This quick communication possibility is one of the main reasons why businesses and organizations prefer two-way radios for their operational or tactical communications.

-Group Communication

An additional unique feature of two way radios is its ability to facilitate “group-calls” or “one-to-many” communications very effectively. This means that one user can easily communicate with one, five, twenty, hundreds, or even thousands of other 2 way radio users simultaneously.

In other words, there’s no need for users to repeat themselves time and again if they need to communicate with more than one user. Moreover, two way radios performs perfectly for group communication using a minimal amount of RF channel-resources. If every user were in the same vicinity the majority of the time, they would only need one-channel resources to speak to hundreds of other users.

WHY NOT SIMPLY USE ANY WIRELESS-SYSTEM?

There is an abundance of wireless-technology today, and they all have their advantages and disadvantages. The choice of which technology is idea for one’s group or association will depend upon if the technology can satisfy the user’s requirements. For users who need to function in a group, communicate instantly, and remain mobile, a two-way radio is the best choice compared to the other wireless technology available on the market today.

You may still wonder how this can be possible with smartphones, iPods, iPhones, tablets, mobile phones available. Here are the main reasons why these technological gadgets may NOT meet the above requirements:

-Instant Communication

Consider this scenario. You are out hiking, run into an emergency situation, and must communicate quickly to confirm your dilemma. If you were using a mobile phone, for instance, you must dial a number, wait while the call is being setup and connected; that’s if you get a signal. The phone must then ring to the other person, and they finally answer, if their voicemail isn’t on! The whole procedure could take several seconds and within that valuable time, your situation could easily worsen.

With a 2 way radio, you simply press the PTT key and yell “emergency” while the other users “immediately” pick-up your signal. This is assuming that RF-channel is accessible. However, there is a way that two-way radios features can surmount RF-channel blockage and give highest-priority to emergency calls, a feature not available to other wireless devices.

-Group Communication

Take this example. You need to let your staff know that there has been some changes for a planned meeting. If you have to contact them one at a time, it could become tedious. With a two-way radio, you can simply select your talk-group, press the PTT key, and begin your message to five, 10, 15, or however many staff members you need to communicate with simultaneously. Now, raise that number to 1000 workers and imagine the work involved if you had to go through cellular phone channels.

Though some wireless systems permit group calls, it usually restricts the amount of group members that you can communicate with at one time. With a two way radio, you simply need to speak once and be heard by many.

WHO USES 2 WAY RADIOS?

Two-way radios have been utilized for many years by numerous industries and associations. Because of the nature of their operational requirements, they use two way radios to broadcast their operational and communicational needs. Organizations and industries that may depend on two-way radio usage are:

-Public Safety associations such as EMS emergency medical services, police, ambulance service, fire brigade, disaster-recovery agency
-Security like intelligence agencies and military
-Transportation industries like subway, railways, seaports, airports, subways
-Oil and gas companies
-Utility companies like cable TV, telephone, water, gas, electricity
-Construction companies for road and bridges, residential, commercial
-Transport service companies like trucks, limos, taxis
-Hospitality industries like tourism, restaurant, resort, and hotel
-Service industry such as towing and delivery companies
-Government agencies like public works, embassies, municipal, district governments, and ministries
-Manufacturing
-Contractors for roofing, plumbing, excavating, electrical
-And many more…

Overall, those who utilize two-way radios are frequently businesses or agencies with many staff members or workers who work in groups and are mobile.

TWO WAY RADIOS TODAY

Today, two-way radios come with additional or improved features from years before. For example, display screens show important information at a quick glance, keypads lock to maintain channel settings, there are various ring-tones and silencers to choose from along with out of range alerts, and much more!

What is Communications Technology?

Broadly speaking, the term ‘communications technology’ can refer to any technology that allows its users to communicate with one another. Using this (admittedly loose) definition, two-way radios and mobile phones fall into the category of ‘communications technology’.

The term also refers to computers and computer-related work. Here in the UK, schoolchildren study a subject called ‘ICT’ this stands for ‘Information and Technology’ (although when this rapidly ageing writer was at school, it was known simply as ‘IT’ or, ‘Information Technology’).

As the Internet has become a more and more prevalent part of our society, communications over longer distances have become significantly easier. In fact, such communications are easier now than at any other time in Human history. Ergo, it stands to reason that computers should be considered as a prime form of communications technology.

Basic, everyday acts such as checking your emails, updating your Facebook or Twitter feed, answering the phone, or taking Skype calls are all a part of ‘communications technology’ as are the two-way radios used by public transport, security firms and the emergency services.

A person who makes a living by working with ‘comms tech’ is likely involved in the designing, creating, implementing or maintaining of communicational systems. Such systems can include radio networks, mobile phone providers, telephone companies, even television. It is a broad and ever-expanding field, which makes it difficult to ascertain exactly what a person actually does if they list it as their job title.

When somebody tells you that they are a plumber, for example, you get a broad idea of what they do for a living all day. If I tell you that I am a professional copywriter, you at least have some notion as to what that entails. A person who works in the field of ‘comm tech’ could be doing almost anything.

In case you’re wondering, the Internet itself can be considered as a communication technology, given that any person who uploads videos or writes blogs is communicating the very second that those blogs are read or those videos are watched.

Telecom’s is a huge field and, as I think you’ll agree, a pretty important one. Without the ability to communicate with others, either via short distances on your mobile or much longer distances (such as the distance between our office in the UK and your home on the African continent), this world would be a vastly different place.

How 2 Way Radios Work

To put it simply, a two way radio is a device that can both receive and transmit voice messages. In broader terms, it can be said that most wireless communication, and it may include cellular systems, fall under the definition. However, these days, 2 way radio is a term to describe radio system for group call communication. The two way radio comes in several technical names such as Public Access Mobile Radio, Private Mobile Radio, Land Mobile Radio and Professional Mobile Radio. These present times, 2 way radios are often called “walkie talkies”. There are several kinds of two way radio systems and some are able to make use of base and mobile configuration, while some re able to utilize a radio network infrastructure.

A typical 2 way radio includes a PTT button, also known as Push-To-Talk button. The button activates the transmitter and the user simply needs to talk to the device to start communicating. The user must release the PTT button in order to receive transmissions from the other line.

A two way radio is able to communicate with other radio devices. However, direct radio communication has very limited range. To overcome the problem, a radio network infrastructure may be used to extend the range of communications. The rest of the article is going to cover more details about how 2 way radios work and other useful information.

Receiving Radio Waves

Just like other forms of Wireless communications, a 2 way radio sends messages over the air. In order to achieve this, the antenna of a way radio contains a specific set of electrons. If the two way radio features multiple channels, then there is specific sets of electrons are each channel. Whenever a radio transmission is received by the 2 way radio, the electrons get excited. The electrons then create electrical impulses. Electrical impulses are then sent to a small processor, which will then convert the electrical impulses to words and sounds that can be understood by humans. The sounds are produced by the speakers within that the way radio.

Keep in mind that there are always radio waves are floating in the air. Because of it, there is always a nondescript sound that may be produced by the two way radios. To solve the issue, a lot of 2 way radios feature a “squelch” setting; and with it, the user can adjust the signal threshold for clearer communications.

Sending Transmissions

Two way radios can also send messages across the air. The main idea is to convert the sound to radio waves. However, the defining characteristic about the way radio is its ability the convert back the radio waves back to legible sounds.

Whenever a user speaks into a 2 way radio, a membrane within the device will vibrate as a response to the sounds. The vibrations are sent to the processor, which in turn converts them to electrical impulses and readies it for transmission.. Finally, the transmission is sent to the antenna which is then broadcasted in the form of radio waves. These radio waves are then received by another device and convert them back to a legible sound.

Multiple Channels

As two way radios are getting more and more popular, it is possible for more than one party communicating in the same line or frequency. This can cause a lot of confusion and interference. To solve the problem, modern 2 way radios are able to utilize multiple channels.

For a two way radio to broadcast on multiple channels, the device must be able to generate radio waves in multiple frequencies. Furthermore, the device must be able to send frequencies with very little fluctuations. These fluctuations are actually caused by the transmitted voices. The fluctuations can be minimized through “frequency modulation”. The modulated transmissions are then sent to the device’s antenna.

The device must also excite the proper electrons. Once the proper electrons are excited, an outgoing radio wave is then produced.

These radio waves may be picked up by another device tuning into the same frequency. Furthermore, the device must be within range of the transmitting device. The range of two way radio is usually determined by a couple of factors such as atmospheric conditions, radio’s battery power and the size of the two-radio’s antenna.

Whenever a device picks up the transmission, the receiving radio must filter the signals through an electronic filter known as a bandpass filter. Finally, the transmission is then converted back to sound.

Why Choose A 2 Way Radio

The two way radio is one of the earliest forms of wireless communication. However, in today’s modernized communication environment, a question arises – is the way radio a viable technology? The answer to that question is a yes. This is because the 2 way radio has its own unique advantages that may not be found in other forms of wireless communications. Below are two of them:

Instant Communication – the ability to communicate between two or more parties almost instantly is one of the most defining advantages of the two way radio. A user only needs to press the “Push-To-Talk” button and within seconds a receiver will be able to receive the audio messages. Furthermore, the entire system is set up around the idea of “quick call” and “quick receive”. This is the main reason why the organizations rely on the 2 way radio technology for operational and tactical communications. The system can also make use of encryption technology for a more secure communication.

Group Communications

Another unique advantage of two way radio is its ability to facilitate “group call” or “one-to-many” communications very efficiently. By efficient, it means that the user can communicate with one, hundreds or thousands at the same time. There is no need for a user to repeat the same message if he/she needs to communicate to more than one individual.

A 2 way radio is one of the earliest technologies used for wireless communications. Even though it is a bit outdated compared to other forms of wireless communications, but the usefulness is still very applicable today. The main idea of how 2 way radios work revolves around on sending and receiving radio waves, which in turn is converted to legible sounds. The idea and technology behind two way radio may be simple, but nevertheless it is still a very well-used form of communication in today’s world.

What’s Lateral Communication

The term ‘lateral communication’ can actually mean (at least) two different things.

In the natural world, lateral communication occurs whenever a group of animals appear to exhibit a collective intelligence. For example, when a flock of birds turns at the exact same time, remaining in perfect formation, this is lateral communication. Other examples include shoals of fish acting in perfect synch, or the movements of ant colonies.

In the business world, however, the term ‘lateral communication’ denotes something else entirely. In modern business, lateral communication is all to do with hierarchy. An example of lateral communication occurs when two workers on the same level discuss ideas (e.g. a manager talking to a manager). Its opposite term, ‘diagonal communication’, occurs when communication is initiated between different levels of hierarchy (e.g. talking to your boss’ boss, or your boss talking to you).

From Wikipedia:

“The term lateral communication can be used interchangeably as horizontal communication. In his text entitled “Organizational Communication,” Michael J. Papa defines horizontal communication as “the flow of messages across functional areas at a given level of an organization” (Papa and Daniels 55). With this system people at the same level are permitted “to communicate directly without going through several levels of organization” (Papa and Daniels 55). Given this elasticity, members within an organization have an easier time with “problem solving, information sharing across different work groups, and task coordination between departments or project teams” (Papa and Daniels 56). The use of lateral or horizontal communication in the workplace “can also enhance morale and afford a means for resolving conflicts (Koehler et al., 1981) (Papa and Daniels 56).”

The pawns, on the other hand, can only converse one space at a time and only in one direction. Oh wait; I’m getting confused again!

 

What Is An Earpiece?

In general context, an earpiece is anything which becomes purposeful when it covers the ear or hangs near it. This means that an earpiece could be used as a general term for several related items which include eyeglass frames, headsets and anything else whose design allows it to fit into the ear and the block entry of sound waves. However, the most common description of an earpiece is that of an electronic device that is used to convert electronic signals into sound waves which are then directed to the ear’s canal; devices in this category can also be referred to as electronic-acoustic transducers.

In the past, the only way of listening to electronic-audio signals generated by a device was through the earpiece. However, with time, amplifiers were developed which made it possible to listen to audio via speakers. This did not render the earpiece useless; on the contrary most people use them as a preference for personal reasons which could be privacy, allowance for hands free operation or for listening to audio playbacks in good quality where there is a lot of noise. Depending on the design, devices can be described as headphones, ear buds, headsets or stereo phones.

Earpieces can be put into two categories which again depends on design and how the device functions. If an earpiece connects to the source of sound via cable, then it can be described as a wired earpiece which came before the cordless or wireless earpieces. Wireless headphones or earphones are similar in design to conventional earpieces of their kind only that they connect to the source of sound via infrared signals or radio waves. Some of the devices which are compatible with the wireless type include mobile phones, computers, CD players, MP3 players and gaming consoles with Bluetooth or Wi-Fi adapters.

Wired earpieces are convenient to some extent but the wire which dangles from a user’s ears to the device they intend to listen to can be disturbing at times. Remember, a wired earpiece has to connect to the sound producing device physically. This means that you will have to bear with dangling motion of the wire although some are designed to be spiral so that the move less. The most common earpieces come with the 3.5 millimeter (0.2 Inch) jack which has been made a standard though introduced by Sony in 1979. Before the 3.5 millimeter jacks came into existence, ¼ inch jacks were the standard. Today, there are still in use but only for professional equipment like that from EarpieceOnline.

Ear buds have not been in the market for long but what makes them worth mentioning is their design which completely changes how the user perceives sound. An ear bud feeds sound directly into the ear drum which is unnatural because the waves bypass the acoustic contouring provided by the listener’s outer ears and head. This way, the user’s brain will assume the sound is in a straight line in the head and between the ears; the result is sound which does not have the three dimensional effect which is normally provided by loud speakers due to the configuration between them and the users ears.

Depending on their configuration, earpieces can further be classified according to their shapes and sizes. For instance, circum-aural headphones come with large pads which surround the outer ear and are the kind used in most professional recording studios. The other type in this context would be supra-aural headphones which fit over the ear without surrounding it. Ear buds which were discussed earlier fit into the ears outer canal but do not fully cover it which means external sounds from other sources are still audible around them. Canal phones which make the fourth category fit snugly into the ears canal and are therefore effective in blocking exterior sounds.

Noise cancellation is a feature which is slowly gaining popularity with the public. The technology works to improve the quality of sound reaching the ear drums by cancelling out other sounds from external sources. The most advanced noise cancelling headphones utilize a physics principle called destructive interference where the headphones produce sound of equal wavelength with noise so that they cancel out. Note that noise cancelling headphones direct some of their sound outwards so as that it cancels noise coming from exterior sources. If you plan to buy earpieces, list down the specifications you would want to avoid purchasing something which will later frustrate you.

How did people communicate with each other 100 years ago?

I presume you mean to ask me how people communicated over long distances, because otherwise the answer would simply be ‘they talked to each other, just as they do today’. I’ll give you the benefit of the doubt, but please be more specific in future! (Kidding!)

OK, so 100 years ago, in 1914, the telephone was still in its infancy, relatively speaking. 99 years ago, Thomas Watson made the first coast-to-coast phone call in America, so that should give you some idea of where the telephone was, development wise.

However, the invention had been patented since 1876 and 1877 had seen the first long-distance phone call placed. But by and large, telephones were not an overly common part of people’s lives the way they are now.

More common was the telegraph, which had been knocking around for a while by then. People in official positions tended to use that, but it wouldn’t have been a fixture of regular people’s houses.

Far more common than telephone or telegraph was the postal service. In 1914, if you wanted to contact a friend, relative, or loved one, you wrote to them. The working classes were better educated than at any other time in history (up to that point) and literacy was improving (although it certainly wasn’t at the near-ubiquitous level of today). Letters took a long time to arrive by today’s standards, so they tended to be longer and more absorbing than, say, a Facebook chat is today. In fact, intellectuals, authors and politicians would often engage themselves in long-winded and exhaustive intellectual contests via thorough, essay-length correspondences.

Another option would have been to speak via mutual acquaintances. Literature of the period frequently involves friends using a mutual friend in order to carry on a long-distance discussion and it is my understanding that this was quite a common practice. Interestingly, this may very well have shaped the development of certain customs in society (such as ‘good manners’ vs. ‘bad manners’ regarding correspondence etiquette). With our communication methods of today being so vastly different, it remains to be seen how our society will come to reflect this.

What Is Meant By The Term Privileged Communications

‘Privileged communication’ is a legal term, applied in many Western countries (including both mine and yours, unless I’m very much mistaken), that applies to any interaction that is required, by law, to remain confidential.

Critically, the law cannot force disclosure in these cases and the party that initially started the communication has the legal right to stop the second party from revealing any information pertaining to the discussion, even in a court of law.

According to ‘Investopedia.com’,

“Typically, privileged communications refer to communications between attorney and client, accountant and client, doctor or therapist and patient, priest and parishioner or husband and wife (and, in some states, reporters and their sources). The recipient of the information must keep the communication private, unless the privilege is waived by the discloser of the information.

There are conditions that must be met in order to preserve the confidential status of these communications. First, the communication must be between people in a legally recognized protected relationship. Next, the communication must take place in a private setting, where the communicators have a reasonable expectation of confidentiality (like a private office). Lastly, the privileged status of the communication is lost if or when the communication is shared with a third party that is not part of the protected relationship (however, agents of the recipient of the information – such as an accountant’s secretary or a doctor’s nurse – would generally not be considered a third party that defeats the privileged status of the communication)”.

I must point out at this time that the ‘Hey, Chris’ column is NOT an example of privileged communication. In fact, in my entire life, I severely doubt that anyone who has ever had a conversation with me has ever felt ‘privileged’ about it in any way. SOB!

I hope that answers your question, Jamal.
